Four servings: two 32 g bread slices plus 100 g cooked chicken, 50 g avocado flesh, 50 g tomato and one-quarter of yogurt, lemon juice, pepper and salt per serving. All toppings counted; no butter or oil. Equipment: Toaster; mixing bowl; fork; knife and cutting board; kitchen scale. Assemble just before eating for the best texture. Keep chicken mixture covered at 40°F or below and use within 3–4 days of the chicken’s original cooking date, or sooner if its storage history requires it. Store bread separately. Refrigerate cut avocado and tomato promptly and use within 1 day for this meal-prep plan; avocado may brown. Do not freeze assembled toast. Keep the cold filling out no longer than 2 hours, or 1 hour above 90°F. No reheating is required for freshly assembled toast with safely chilled cooked chicken. Timing is a development estimate and has not been kitchen tested. Nutrition is Estimated, not Reviewed. No optional toppings included.
